Effects of Sodium Hydroxide Solutions on the Permeability of Magnesium Clays
Relationships for permeability of kaolinite versus degree of saturation and permeability versus flow are developed for 0.005 N calcium sulphate, xylene and aniline permeants using the triaxial flexible wall permeammeter. The clay was statically compacted at degrees of saturation of 50%, 75%, and 100%. A gradient of 277 was used for the permeability tests. The initial degree of saturation was inversely related to the permeability of the clay. Saturated clay samples were found to be virtually impervious to aniline and xylene. As the degree of saturation decreased, the permeability increased with the initial volume of flow equivalent to the volume of air space and saturating the sample. Subsequent flow occurred at a stabilized permeability. The stabilized permeability is independent of the initial degree of saturation for the standard permeant (0.005 N calcium sulphate).
